Marathon Training — Week 2 Reflection

Interval running.
Intensity breeds results. Long distance running, sometimes referred to as Zone 2, builds your aerobic capacity. Getting out there and putting in the one, two, even three hours at a time is an excellent was to develop your energy pathways. Long distance helps to teach your body to source fat for energy. The better your body uses energy the more efficient your running is.

Similar to many energy consumption processes, some waste is created when running. Cars emit excess gas; fire leaves charred remains; likewise, your body produces lactic acid. Although lactate is necessary to continue the energy turnover in your body, too much of it is slows us down.

If we can drive up the lactate threshold, less lactic acid will be produced when running. A very effective way to do that is to perform sprint repeats at high intensity. This past week we focused a training day on 400 meter repeats. The 400 is an excellent mid range sprint.

The point is to run as hard as possible while maintaining even paced times. For example, we ran five repeats this week. Our general pacing guideline was to hit 90 seconds each repeat, plus or minus 2 seconds. Depending on your conditioning you may want to adjust that up or down, but aim for the same times each leg.

How much rest is ideal between each sprint? Tune in next week to find out. (Same Bat channel, same Bat time.)
